beam off grid line ???
i think the best solution if nothing opposes it is to put a beam supporting the inner part parallel to the façade and then whatever protrusions in plan, whether with walls or only parapet or railings be taken in cantilever from the beam. we use this solution systematically, if only because in practice many times the point of support at the outermost façade walls would fall in the street.
as long the cantilever is proportionate one needs not to expect special problems; sometimes a hairline crack develops even in these, but this is more common when the number of strories goes high and the length of the cantilever becomes significant.
but you must make the thicknesses of such size as to no deflection problems develop. for example, 10 cm thickness for a 60 cm cantilever loaded by a wall might show some deflection distress that analysis of the deflections should show.
